Description

Create a design and simulate using EE-Sim^® tools:

The MAX4273 evaluation kit (EV kit) is a fully assembled and tested surface-mount hot-swap controller circuit board that provides current-limiting and DualSpeed/Bi-Level™ fault protection. The circuit uses a MAX4273 IC in a 16-pin QSOP package and is configured for a +2.7V to +13.2V input voltage range.

The MAX4273 controls the N-channel MOSFET and provides current regulation during startup. Several configurations allow the MAX4273 IC’s unique current regulation architecture to be tailored to the application. The current-limiting and short-circuit protection features are configurable and demonstrate the various features provided by the MAX4273 IC.

The EV kit features a power-on reset (POR) circuit. Several configurations for autoretry, glitch filters, auxiliary V_CC power, and gate drive speed are provided. The EV kit can also be reconfigured to emulate the MAX4271 and MAX4272 hot-swap controllers.
